A music teacher is accused of dropping his trousers in front of a colleague and boasting about the size of his manhood.

Alex Wynne Jones, who worked at various schools in Denbighshire through the Denbigh Music Co-operative, had become "increasingly erratic" in his behaviour, a fitness to practise hearing was told.

On one occasion he was said to have serenaded two women, which colleagues found "excruciatingly embarrassing".

It is also alleged Jones told a pupil she was gorgeous, gave her his phone number and offered to teach her to play the piano.

Patrick Llewellyn, who was presenting the case against Jones to an Education Workforce Council panel, said that Jones allegedly encouraged female staff to organise a party at his house, and asked one assistant to get the phone number of a colleague whom he fancied.

Jones, 42, visited a colleague, who worked at Ysgol Plas Brondyffryn in Denbigh, and grabbed her and tried to kiss her.

Mr Llewelyn said: He dropped his trousers, exposing his penis and said ‘Look how big it is’.”

The hearing was told that in November, 2016, Jones was twice breath-tested by the police while on his way from Prestatyn High School and Ysgol y Faenol, Bodelwyddan, and although he was under the drink-drive limit, he was believed to have drunk alcohol before teaching.

He was suspended by the county council but ignored the suspensions to attend both Prestatyn High School and the Blessed Edward Jones High School in February, 2017.

David Price, assistant head of Ysgol Plas Brondyffryn in Denbigh, said that when he took over as acting head in September, 2016, he was advised by his predecessor to keep an eye on Jones, who worked there two days a week, because of his drinking.

Mr Price said he never once smelled alcohol on his breath, but added: “He was constantly eating mints and he wore a lot of cologne.”

Jones did not attend the hearing and was not represented.

The final allegations, also said to amount to “unacceptable professional conduct”, relate to his conviction for careless driving and drink-driving in Stranraer in September, 2018.

He was fined a total of £600 and banned from driving for 18 months.

Mr Price said that regardless of the allegations there had been great concerns about Mr Jones’ timekeeping and attendance, the fact that he was claiming full pay even when he had gone home early, and also about the standard of his work.

“We were getting poor service and poor value for money,” he said.

Jones faces a total of 12 allegations of unacceptable professional conduct.
